Looks like clears. If it's not clicky switch it is definitely clears. Looks exactly like a Leo brand keyboard I saw recently which was also clears. Clears are also 'white' but they are translucent. Whites are very white and solid.
Mine click and are solid white
I saw that Leo board as well, which was my main reason to buy this optimus
I have an issue though which seems like worn out stems...some click some do not
Probably will need to check whole board and swap them around
But all in all it is a fun switch
